Solution for Lightscribe Win32 Error: 1784

Hi All!,
I am posting this for the benefit of others. I just installed a new Sony DRU-835A DVD burner. This has the lightscribe feature. Every time I attempted to burn a label I received the following error:
Event Type: Warning
Event Source: LightScribeService
Event Category: None
Event ID: 1

Description:
Win32 Error : Function: [HurricaneClientProxy:oInputCommand] DeviceIoControl returned Win32 Error: 1784 Description: The supplied user buffer is not valid for the requested operation.

After searching for a while I found a number of references to the issue, but it seems everyone was just returning the drives as bad.
A visit to http://www.lightscribe.com revealed that one of the known issues was a problem with the Intel Application Accelerator. It has a registry setting that conflicts with drive communications. I downloaded the Lightscribe Diagnostic Utility, installed it, ran it and it fixed the problem!!
